Hi maze7817 :blink:

Nice job,

1. Double-click avenger.exe on your desktop.

2. Copy all the text contained in the code box below to your Clipboard by highlighting it and pressing (Ctrl+C):

Files to delete:
C:\WINNT\system32\v7.exe
C:\WINNT\system32\mswsock.bak


Note: the above code was created specifically for this user. If you are not this user, do NOT follow these directions as they could damage the workings of your system.


3. Now, start The Avenger program by clicking on its icon on your desktop.
  • Under "Script file to execute" choose "Input Script Manually".
  • Now click on the Magnifying Glass icon which will open a new window titled "View/edit script"
  • Paste the text copied to clipboard into this window by pressing (Ctrl+V).
  • Click Done
  • Now click on the Green Light to begin execution of the script
  • Answer "Yes" twice when prompted.
4. The Avenger will automatically do the following:
  • It will Restart your computer. ( In cases where the code to execute contains "Drivers to Unload", The Avenger will actually restart your system twice.)
  • On reboot, it will briefly open a black command window on your desktop, this is normal.
  • After the restart, it creates a log file that should open with the results of Avenger’s actions. This log file will be located at C:\avenger.txt
  • The Avenger will also have backed up all the files, etc., that you asked it to delete, and will have zipped them and moved the zip archives to C:\avenger\backup.zip.
5. Please copy/paste the content of c:\avenger.txt into your reply

Next,

Please go to UploadMalware to upload a suspicious file for analysis.
  • Enter your username from this forum
  • Copy and paste the link to this thread
  • Browse for this filename: C:\avenger\backup.zip
  • In the comments, please mention that I asked you to upload this file
  • Click on Send File
Now delete your current combofix, then download it again from Here to your Desktop and run scan again, post the results in your next post.

And one final scan with Kaspesky :help:

Please do an online scan with Kaspersky WebScanner

Click on Kaspersky Online Scanner

You will be promted to install an ActiveX component from Kaspersky, Click Yes.
  • The program will launch and then begin downloading the latest definition files:
  • Once the files have been downloaded click on NEXT
  • Now click on Scan Settings
  • In the scan settings make that the following are selected:
    • Scan using the following Anti-Virus database:
    Extended (if available otherwise Standard)
    • Scan Options:
    Scan Archives
    Scan Mail Bases
  • Click OK
  • Now under select a target to scan:Select My Computer
  • This will program will start and scan your system.
  • The scan will take a while so be patient and let it run.
  • Once the scan is complete it will display if your system has been infected.
    • Now click on the Save Report As... button:
  • Under Save as type select Text file write name for the file and save it to your Desktop.
  • Locate the file at the Desktop, open it, then copy and paste that information in your next post.
OK, post the contents of the scan reports here, also let me know how is the computer running :whistling:

Hi maze7817 :whistling:

avast! is free for use, all you need to do is to go here http://www.avast.com...egistration.php click on this link "I'm a new user and I need a registration key for avast! Home Edition" then read this Before making your registration, please read the following information:, then fill the form bellow, then click on the Register button. They will send message to your email with registration number in few minutes.
Posted Image

Start avast!, click on Registration, a pop up will show up, copy and paste the registration key that they sent before and paste it here, then click OK button.

Remember, the license key is valid for 1 year. In about one year avast will alert you that your license is going to expire, all you need to do is just to re-register for free again. :blink:

Now please follow the steps from my post before and post the results here!

Hi maze7817 :help:

Glad that your computer is running well now :whistling:

Did you upload C:\avenger\backup.zip at UploadMalware ? If not please first upload the file and after that proceed with deleting files and folders.

Delete this folders/files:

C:\avenger
C:\Documents and Settings\Allen\Desktop\SmitfraudFix
C:\Documents and Settings\Allen\Desktop\SmitfraudFix(2).exe
C:\_OTMoveIt
C:\qoobox\

The following is a list of tools that I recommend to people for better protections and preventing from re-infecting of the computer.
  • SpywareBlaster - Helps preventing spyware from installing in the first place.
  • SpywareGuard - To catch and block spyware before it can execute.
  • IESpy-Ad - Blocks access to malicious websites so you cannot be redirected to them from an infected site or email.
  • MVPS Hosts file - The MVPS Hosts file replaces your current HOSTS file with one containing well know ad sites etc. Basically, this prevents your coputer from connecting to those sites by redirecting them to 127.0.0.1 which is your local computer
  • Comodo BOClean - BOClean runs automatically in the background without interfering with your work and kills malwares INSTANTLY the moment they activate without giving them the chance to invade your machine.
  • SUPERAntiSpyware Home Edition (free version) – Another effective program for helping remove some of the more difficult infections
  • More Secure Browser - Internet Explorer is not the most secure and best browser. There are safer and better alternatives available. I recommend Firefox, and Opera
  • Google Toolbar - Free google toolbar that allows you to use the powerful Google search engine from the bar, but also blocks pop up windows.
Also see So how did I get infected in the first place? :blink:

I will leave this thread open for few days, if you have any questions feel free to ask me!

Yes, you can safely remove following tools: SDFix, haxfix, Dr.Web CureIt, FixWareout, WinPFind3U.exe, dss, and combofix, logfiles too. Delete the folders instructed in my post before. I advice you to keep ATF Cleaner it does good job cleaning tracking cookies etc. Also read my prevention speech, you can find there some nice tools like SpywareBlaster and Comodo BOClean!

Hello maze7817, sorry for the delay.

If you haven't already, you can safely delete this files: find.bat, fixme.reg, blbeta.exe.
And the other two its up to you, if you are not planning to use Process Explorer in future, then you can also delete the next two files procexp.chm, procexp.exe.

As your malware issue is resolved now i will close your thread.

Best regards,
